Overview

• Researchers with the Stone Living Lab documented water spilling onto walkways at Long Wharf on Wednesday during the seasonal high tides.
• King tides are predictable astronomical events when the sun, moon, and Earth align, raising water levels a foot or more above the average high tide in fall and sometimes spring.
• Stone Living Lab reports Boston Harbor’s sea level has risen roughly 10 inches to a foot over the last 100 years, compounding the effects of these tides.
• The team cautions Boston should expect several coastal flooding episodes this fall linked to these higher‑than‑normal tides.
• In response, the lab is working with the city to test nature‑based “living shoreline” adaptations and is engaging residents through a self‑guided High Tide Trail.
